Narrow Green-banded Swallowtail

EASY GARDEN BUTTERFLIES

Narrow Green-banded SwallowtailPapilio nireus lyaeus

Swallowtails are the largest and most charismatic of all butterflies. They are members of the family Papilionidae (Swallowtails and Swordtails). They received this name because those found in Europe possess elongated, swallow-like tails on their hindwings. We now know that not all ‘Swallowtails’ have these tails. 

The Narrow Green-banded Swallowtail Papilio nireus lyaeus has expanded lobes at the tailward corner of the hindwings instead of actual tails. It looks entirely black in flight, but the coloured bands show up well as it flutters its wings. It’s slightly smaller than the Citrus Swallowtail with a wingspan of 75-95mm. Males are slightly smaller than females and are more brightly coloured with brilliant turquoise-blue bands on the wings. The females’ bands are closer to true green, and their ground colour is a less intense black.

Swallowtails seldom settle during the day, preferring to swoop and flutter around flowers and their host plants. When feeding they hover in front of a flower or on a mud puddle, using their legs and feet to steady themselves.

Distribution

Narrow Green-banded Swallowtail is less widespread in South Africa than the Citrus Swallowtail. It’s found on the coastal side of the Great Escarpment from Swellendam in the Western Cape to the whole of KZN, Mpumalanga, Limpopo and Gauteng, also the north-eastern Free State.  It has followed ‘man-made forests’ in cities across the country and has recently moved onto cultivated Citrus as a host plant. 

Outside South Africa it’s found all over sub-Saharan Africa in forests and frost-free savanna.

Egg

Swallowtail eggs are generally similar across the family Papilionidae: tiny pearl-like spheres with flattened bases. They are white when laid, changing colour to pale yellow if fertile and then becoming green with faint brown mottling. Narrow Green-banded Swallowtail eggs are 0.95mm high by 1.15mm diameter.

They are laid on the young shoots and leaves of the host plant, held in place by an adhesive secreted by the mother. The egg stage lasts about five days.

Young caterpillar

Papilio nireus lyaeus

Young Narrow Green-banded Swallowtail caterpillars, like other Swallowtails, resemble bird droppings. When freshly hatched from the egg they are about 3mm long. They are more slender than Citrus Swallowtail larvae with more green colouration.

This camouflage gives them protection against predators like birds, which would not recognise them as a source of nutrition.

They have two rows of short spines along the body with forward-pointing ones behind the head. The tail is forked and also carries short spines. The thorax has longer spines than the rest of the body.

The caterpillars take about 24-30 days to reach full size, undergoing four moults.

Mature caterpillar

Narrow Green-banded Swallowtail fully grown larva

Fully-grown Narrow Green-banded Swallowtail caterpillars are green with pale grey underparts and yellow lines, and the thorax is blue-green.

If disturbed, all stages of this caterpillar will rear up and extrude a forked orange organ called an osmeterium. This emits a strong scent of oils from the host plant. Together with the eyespots on the thorax of a mature larva gives the impression of a small snake, which can startle away small predators.  

The final instar caterpillar takes about a week to ten days to reach a size of 35-45mm.

Pupa/Chrysalis

Narrow Green-banded Swallowtail pupa

Narrow Green-banded Swallowtail

Papilio nireus lyaeus

Narrow Green-banded Swallowtail pupae are attached to leaves or stems of the plant by a tail hook and a silken girdle spun over their ‘waist’. They hang from the girdle as shown here. They are wider than those of the Citrus Swallowtail with fewer projections and a smoother surface.

They are variable in colour from leaf green to pale brown depending on the surface they are formed on. 

The pupa is about 28-30mm long. The pupal stage lasts from two weeks to several months when the insect undergoes diapause as a pupa.

Host plants

Narrow Green-banded Swallowtail caterpillars feed on Rutaceae only; plants like White Ironwood Vepris lanceolata, Small Knobwood Zanthoxylum capense, Cape Chestnut Calodendrum capense,  Slender Cherry-orange Teclea natalensis, and Horsewood Clausena anisata. These are all excellent garden trees and well worth planting.

How to attract them

Gardeners can promote the presence of this butterfly by cultivating its preferred wild host plants. Other Swallowtail species, if present, will lay eggs on them and breed in the garden.

Like most butterflies they welcome open sunny areas with lots of flowers to visit for nectar. Leadwort Plumbago auriculata is a good nectar plant for Swallowtails, which are fond of large pink or red flowers like Coral Senecio, Hibiscus or Cape-honeysuckle. The males also like to suck mineral-laden water from water seeps and river banks. Sprinkling a little bone meal on wet sand may attract this and other butterflies.

Citrus Swallowtail

EASY GARDEN BUTTERFLIES

Citrus SwallowtailPapilio demodocus demodocus

The Citrus Swallowtail is one of the Papilionidae (Swallowtails and Swordtails). Although it’s called a ‘Swallowtail’ its hindwings lack the long tails that its relatives have.

Citrus Swallowtail is a large and conspicuous butterfly with a powerful flight and the restless nature typical of Swallowtails. Males (wingspan 100-120mm) patrol large territories looking for females and food sources. They are often found congregating on wet sand and mud around water sources.

Females (wingspan 110-130mm) are found on flowers and close to their host plants. The sexes are similar; females have an orange tint to the cream ring around a large eyespot at the upper corner of the hindwing (not visible here). 

Citrus Swallowtail is active from spring to autumn but it often peaks in midsummer. This is the reason for its other name, Christmas Butterfly. 

Distribution

Citrus Swallowtail occurs throughout South Africa and is common almost everywhere except remote arid areas with little human habitation. Because it uses the popular cultivated Citrus as a caterpillar host plant it is found in areas where its wild host plants are absent.

Outside South Africa it’s found all over sub-Saharan Africa, the moister parts of the Arabian peninsula, Madagascar and the Indian Ocean islands.

Not all Citrus Swallowtail caterpillars feed on the Citrus family of plants. Some, like this one, use Apiaceae (Umbellifers) and their colouring affords them camouflage when feeding on these plants.

The final instar caterpillar takes about a week to ten days to reach a size of 35-45mm.

Citrus Swallowtail pupae are attached to leaves or stems of the plant by a tail hook and a silken girdle spun over their ‘waist’. They hang from the girdle as shown here.

They are variable in colour from bark-like grey to leaf green depending on the surface they are formed on. Many have patches of green and grey.

The pupa is about 35-38mm long. The pupal stage lasts from two weeks to several months when the insect undergoes diapause as a pupa.

Host plants

Citrus Swallowtail caterpillars feed on plants in the Rutaceae (Rue and Citrus) family, which often grow in gardens. They also use Apiaceae (Umbellifers) like Fennel Foeniculum vulgare. Wild South African Apiaceae like Deverra or Peucedanum species are skin irritants and don’t make good garden subjects. There are many local Rutaceae that this butterfly uses in the wild. Examples are White-ironwood, Vepris lanceolata, Horsewood Clausena anisata, Small knobwood Zanthoxylum capense, and Cape-chestnut, Calodendrum capense.

How to attract them

Gardeners can promote the presence of this butterfly by simply growing a Lemon tree! Some people don’t like the way the caterpillars eat holes in the leaves, although they seldom arrive in sufficient numbers to do real damage. One way to divert their attention from the Lemon tree is by cultivating its preferred wild host plants. An advantage of doing this is that other Swallowtail species, if present, will lay eggs on them and breed in the garden.

Like most butterflies they welcome open sunny areas with lots of flowers to visit for nectar. Swallowtails are particularly fond of large pink or red flowers like Hibiscus or Cape-honeysuckle.

Meadow White

EASY GARDEN BUTTERFLIES

Meadow White Pontia helice

The Meadow White is one of the Pieridae (Whites, Tips and Yellows) subfamily Pierinae (Whites and Tips).

Meadow White is a small to medium-sized butterfly with a wingspan of 35-45mm. Its markings resemble the common migratory Pioneer Caper White Belenois aurota, but it flies more slowly and lower down. It settles often and is fond of flower nectar. It’s a pretty little insect with its underside marked in shades of green and yellow. The sexes are similar, with the female having black marks at the inner margin of the forewing and along the outer margin of the hindwings where the males are plain white.

Meadow White is often one of the first butterflies to emerge in spring. 

Distribution

Meadow White occurs throughout South Africa, particularly in grasslands. It typically does not frequent forests but it can be found almost everywhere apart from the hottest and most humid places. It’s also found in Namibia, Angola, Botswana, Zimbabwe and Mozambique. In East Africa it’s replaced by the Northern Meadow White, Pontia johnstonii.

Egg

Pontia helice

Meadow White eggs are typical of the family Pieridae: bottle-shaped, tapered at the top, with vertical ribs connected by horizontal cross-ribs. They are pale yellow, changing colour to dull orange if fertile. They are 1mm high by 0.5mm diameter, with 12-13 vertical ribs and 30-35 cross-ribs.

They are laid on the flowers, ovaries, and pods of the host plant. The egg stage lasts about five to nine days.

Caterpillar

Fully-grown Meadow White caterpillars are yellow with green underparts and stripes of green and bluish-grey. 

They have rows of black dots and those at the front of each segment are outlined with orange. 

They grow from 1mm to about 20mm in two to four weeks depending on conditions; there are usually four moults.

 

Pupa/Chrysalis

Pontia helice

Meadow White

Pontia helice

Meadow White pupae are attached to leaves or stems of the plant by a tail hook and a silken girdle spun over their ‘waist’. This holds them tight to the surface; they don’t hang down from the tail like Nymphalidae or from the girdle as do Swallowtail pupae and some other Pieridae.

They are variable in colour, some being greyish-green with yellow stripes, or pale purple or grey-brown with yellow stripes.

The pupa is about 18mm long. The pupal stage lasts from four days to two weeks depending on climate conditions.

Host plants

Meadow White caterpillars feed on plants in the Brassicaceae family, which often grow in gardens. Indian Mustard Brassica juncea, Garden Alyssum Alyssum minutum, and Cultivated Rocket Eruca sativa are popular host plants. In the wild they occur on Virginia Peppercress Lepidium virginicum and its relatives. It also uses Hedge-mustard Sisymbrium officinale and Yellow Mignonette Reseda lutea.

Meadow White is the only member of the African Pieridae that it’s easy to get onto garden plants. To market gardeners who grow Indian Mustard and Rocket commercially it’s seen as a ‘pest’ but the caterpillars are solitary. They are far less destructive than the invasive Cabbage White Pieris brassicae to which this butterfly is related.

Like most butterflies they welcome open sunny areas with lots of flowers to visit for nectar.

Garden Commodore

EASY GARDEN BUTTERFLIES

Garden CommodorePrecis archesia archesia

The Garden Commodore (aka Garden Inspector) is one of the Nymphalidae (Brush-footed Butterflies), subfamily Nymphalinae (Admirals, Pansies etc.).

As its name suggests, this is a butterfly found often in gardens. Commodores are related to Pansies and have similar behaviour and habits, but there are some significant differences like their choice of caterpillar host plant.

Another difference is that whilst Pansies vary slightly in appearance with the seasons a winter form Commodore looks very different to a summer form one. Summer form Garden Inspectors are brown with conspicuous cream to buff-orange bands. Winter (dry season) forms are also brown, but have bands of maroon-red rather than buff to orange, and blue spots and bands on their forewing tips and outer edges. Their wingspan is 45-55mm. 

They are sun loving butterflies, but the two forms behave differently. Summer forms are found in open country where they frequent hilltops and bright sunny places. Winter forms tend to hide up in shady places and only come out on sunny days. The males are aggressively territorial and will choose a high point and chase away all other butterflies from it.

Distribution

Garden Commodores occur on the eastern side of South Africa, in grassland and savanna from Plettenberg Bay to Swaziland. Gauteng, Mpumalanga and Limpopo as well as the eastern side of North-West Province.

The species is found across Africa south of the equator in suitable habitats.

Egg

Commodores are closely related to Pansies and Diadems and have similar eggs. The Garden Commodore’s egg closely resembles that of the Southern Gaudy Commodore: green, barrel-shaped, tapered towards the top with 12-14 white vertical ribs that don’t reach the apex, with faint cross-ribbing. They are laid on young shoots of the host plant, singly or in small groups. They are about 0.7mm diameter by 0.6mm high. The egg stage lasts three to five days, taking longer in cool conditions.

Caterpillar

Fully-grown Garden Commodore caterpillars are entirely dark brown to black. The head has two short spiny horns. The body has seven rows of branched, black spines, one per segment. These are shorter than the spines on a Gaudy Commodore caterpillar. Although spiny they don’t sting or make you itch. They grow from 1.5mm to 42-46mm long over a month. There are normally four moults but when growth is slow there can be five. 

Pupa/Chrysalis

Garden Commodore pupae are similar in shape to those of Diadems and Pansies, with short spines on the back. The colour varies from dark brown to black, with a band of silver across the wing cases and abdomen.

The pupa is about 25mm long. The pupal stage lasts from two to four weeks depending on climate conditions.

Host plants

Garden Commodore host plants are in the family Lamiaceae: Sages, Mints and cultivated Coleus, in the genera Plectranthus and Coleus.

Favoured plants are Blue Boys Coleus livingstonei, Spike Spurflower Coleus subspicatus, Lobster bush Coleus neochilus, and Tall Spurflower Plectranthus ecklonii.

Like its close relatives the Pansies and Diadems it’s a sun-loving insect that’s often found on flowers. Males like to patrol hilltops and other prominent landforms.

Commodores and their relatives seek out sheltered places in winter to hibernate as adults. They often enter houses and hide behind the curtains, or sneak into tool sheds.

Southern Gaudy Commodore

EASY GARDEN BUTTERFLIES

Southern Gaudy CommodorePrecis octavia sesamus

The Southern Gaudy Commodore is one of the Nymphalidae (Brush-footed Butterflies), subfamily Nymphalinae (Admirals, Pansies etc.).

Southern Gaudy Commodore is well-named because it’s one of the most brilliantly coloured medium-sized butterflies we have in South Africa. It’s the largest of our Commodores with a wingspan of 50-65mm. It’s also a superb example of seasonal dimorphism.

A winter form Gaudy Commodore looks very different to a summer form one. Summer form Gaudy Commodores are brilliant pinkish red to orange. Winter (dry season) forms were once thought to be a completely different butterfly species. They are deep iridescent blue that shifts in hue depending on the angle of view. This is set off by a band of red spots on the outer edge of each wing. The underside of this form is almost black.

As with the related Garden Inspector the two forms behave differently. Summer forms are found in open country where they frequent hilltops and bright sunny places. Winter forms tend to hole up in shady places like riverbanks and culverts and only come out on sunny days. The males are aggressively territorial and will choose a high point and chase away all other butterflies from it.

‘.

Distribution

Southern Gaudy Commodores occur along the coastal littoral and lowveld from East London to northern Limpopo as well as in the Drakensberg and other mountains and their foothills. They’re common in grassland habitats that have sufficient rainfall to support their host plants and rocky areas to provide shelter. They can withstand cold conditions because of their habit of hibernating in dark, sheltered places.

Southern Gaudy Commodores are found in Africa south of the equator. Its northern cousin Precis octavia octavia (which it resembles closely) occurs across Africa south of the Sahara to the equator.

Egg

The undersides of butterflies can look very different to their upper sides, so it helps to be able to recognise them. Also, Gaudy Commodores have a ‘change of the guard’ in spring and late summer. Occasionally (and very rarely) you might see one that is in between the summer and winter forms. This is the rare form transiens. They vary a lot. Some look like winter forms with a splash of summer form colour along the edge of the wings. Others are more of a mixture, with shades of pink or purple.

Common Diadem

EASY GARDEN BUTTERFLIES

Common DiademHypolimnas misippus

The Common Diadem is one of the Nymphalidae (Brush-footed Butterflies), subfamily Nymphalinae (Admirals, Pansies etc.).

The male Common Diadem is an amazing sight. His upper side is jet black with a large white blotch in the middle of each wing. Each blotch is ringed with a shifting iridescent blue lustre which is only visible from certain angles. His underside is attractive as well. 

This butterfly is an example of what we call sexual dimorphism, in which females and males look totally different. The female Common Diadem looks like an African Plain Tiger, because she mimics that butterfly to gain protection against predators who have learned to avoid that bad-tasting butterfly. 

The Common Diadem’s wingspan is like that of an African Plain Tiger – 60-80 mm.

A Common Diadem has a more nervous and active flight than an African Plain Tiger, and when it lands it will constantly move its wings up and down. We call this ‘pumping’.

Distribution

The Common Diadem is found across the eastern side of South Africa, avoiding the arid Nama Karoo and Succulent Karoo areas. It’s found in the fynbos areas of the Western Cape and has spread across the world, being found across Asia and the Americas where it’s known as the Danaid Eggfly.

It’s widespread in Africa and it’s found on the southern end of the Arabian peninsula as well as Madagascar and the Indian Ocean islands.

Egg

The body has seven rows of short, branched, black spines, one per segment. Although spiny they don’t sting or make you itch. They grow from 2mm to 48-50mm long over a month. There are normally four moults but when growth is slow there can be five. 

Pupa/Chrysalis

The Common Diadem pupa is variable in colour, from sandy to black through various shades of brown. It closely resembles that of a Pansy or Commodore, having the rounded shape with spiny back typical of Nymphalinae pupae. It’s usually formed concealed on the host plant or in leaf debris where it is well camouflaged. Like all Nymphalidae pupae it is attached to its substrate by its tail. The pupa is 22-25mm long and the adult usually emerges after 4-6 weeks.

Host plants

Like many widespread butterflies, Common Diadem has a wide host plant range. In South Africa its main host plant is African Coromandel Asystasia intrusa, but it also uses Justicias like Veld Justicia Justicia protracta, Moss-rose Purslane Portulaca grandiflora, and Ruellias like Veld Violet Ruellia cordata.

African Grass Blue

EASY GARDEN BUTTERFLIES

African Grass BlueZizeeria knysna knysna

African Grass Blues are tiny (wingspan 18-24 mm), low-flying butterflies in the Lycaenidae (Gossamer-winged Butterflies), subfamily Polyommatinae (Blues, Bronzes, Hairstreaks etc.). Blues are tiny to small butterflies, many of which have brilliant blue uppersides (although some are dull grey or brown). 

The sexes differ slightly on their upper sides. Male African Grass Blues are shiny violet-blue above with a well-defined grey wing margin. They differ from their females which are charcoal grey with the bases of the wings being sky blue with ill-defined margins. The underside of both sexes has patterns of grey-brown spots and arrow-marks on a whitish grey ground.  

African Grass Blues fly very low and spend most of their time in the grass – hence their common name. They feed on low-growing flowers and like to sit on damp earth and mud, sucking up dissolved minerals. The sexes fly together and engage in courtship when they encounter one another.

 

Distribution

African Grass Blues are found all over South Africa except for the central Nama Karoo and the highest altitude grasslands. They are common all over Africa, Madagascar, and the Indian Ocean islands. The Asian Grass Blue subspecies Zizeeria knysna karsandra is found in North Africa, southern Europe, the Middle East and across tropical Asia to Australia.

Egg

Zizeeria knysna knysna eggs

Female African Grass Blues lay tiny, pale blue-green eggs singly on buds or flower stalks of the host plant. They turn white as they mature. They are flattened disks 0.5mm in diameter by 0.25mm high.  They have double rows of whorled white ribs that are joined by horizontal ribs on the side to create a pattern of triangles with a tiny mole where they meet. There is a prominent dark mark at the centre of the top. The egg stage lasts about five days.

Caterpillar

Zizeeria knysna knysna

Zizeeria knysna knysna

African Grass Blue caterpillars are tiny. They are slug-shaped, as are most caterpillars of the Lycaenidae. Fully-grown caterpillars vary in colour from pale green to dull mid-green, with pale whitish diagonal side markings and a pale stripe along the back. The skin is covered in tiny bristles and appears velvety. Young larvae eat slots into the leaves of the plant and conceal themselves in those. Older larvae wrap themselves around a leaf and consume it – they are very hard to see when they do this. They grow from 0.8mm to 10-11mm long in three moults over two to three weeks. They have a ‘honey gland’ on their rear segments like many other Lycaenidae, which attracts the attentions of ants. 

Pupa/Chrysalis

Zizeeria knysna knysna

African Grass Blue

Zizeeria knysna knysna

African Grass Blue pupae are covered with tiny bristles. They vary in colour from pale yellow-green to darker green with a varying amount of grey speckling. The caterpillars pupate in debris below their host plant. They are attached by tiny hooks on their tail to a silken pad spun by the larva and by a silken girdle around their ‘waist’. They are about 7-8mm long, and of a typical rounded Lycaenid shape. The adult normally emerges in about one to three weeks although it can be longer in cold or dry conditions.

Host plants

African Grass Blue caterpillars feed on a variety of plants from various families. One of the best-known is the Creeping woodsorrel, Oxalis corniculata – a common lawn weed found all over Africa. Few gardens will not have these little Blues flying around their lawn. Not all gardeners are fond of this plant and even fewer like one of its other host plants, Devil-thorn Tribulus terrestris!  It also uses plants in the Pea family, Fabaceae, like Lucerne, Medicago sativa

How to attract them

It’s very difficult to prevent this little species from appearing in a garden because a main host plant is a widespread lawn weed! This is one of the best arguments for avoiding weed killers and insecticides, accepting biodiversity into the lawn environment. Think of Creeping woodsorrel as an attractive ground cover with benefits!

Zebra Blues

EASY GARDEN BUTTERFLIES

Zebra BluesLeptotes species

Zebra Blues are small (wingspan 20-30 mm) low-flying butterflies in the Lycaenidae (Gossamer-winged Butterflies), subfamily Polyommatinae (Blues, Bronzes, Hairstreaks etc.). Blues are tiny to small butterflies, many of which have brilliant blue uppersides (although some are dull grey or brown). 

The image with upper sides shows a pair in courtship mode prior to mating. Male Zebra Blues (left) are shiny blue above and differ from their females (right) which have a checkerboard pattern of grey on a white and blue ground. The undersides have irregular grey stripes on a white ground, resulting in their common name. Like many Lycaenidae they have short hindwing tails positioned next to prominent eyespots (particularly on the underside) that create a predator-confusing ‘false head’ effect.

There are four species of Leptotes Zebra Blue. Common Zebra Blue Leptotes pirithous, Short-toothed Zebra Blue L. brevidentatus, Jeannel’s Zebra Blue L. jeanneli, and Babault’s Zebra Blue L. babaulti, which have identical wing markings to one another. The only way to tell them apart is to dissect them and that means killing the butterfly. Who wants to do that? Most of the ones we see are the Common Zebra Blue; it really is just that; common!

Males choose a perch on top of a bush or on a prominent rock and fly off to chase other butterflies. They settle often and readily open their wings to reveal the upper side. They also like to sit on damp earth and mud, sucking up dissolved minerals. They may also suck nutrients from old bones or carnivore dung. Females are found close to the host plants or on flowers.

Distribution

Zebra Blues are found all over South Africa except for the central Nama Karoo and the highest altitude grasslands. They are common all over Africa, the southern Arabian peninsula, Madagascar, and the Indian Ocean islands. The Common Zebra Blue is found in Europe and even reaches the south of England, where it rejoices in the name ‘Lang’s Short-tailed Blue’! 

Egg

Leptotes pirithous

Leptotes pirithous

Female Zebra Blues lay tiny, pale blue eggs singly on buds or flower stalks of the host plant. They turn white as they mature. They are flattened disks 0.5mm in diameter by 0.3mm high.  They have double rows of whorled white ribs that are joined by horizontal ribs on the side to create a pattern of triangles with a tiny mole where they meet. There is a prominent dark mark at the centre of the top. The egg stage lasts about six to seven days.

Leptotes pirithous

Zebra Blue caterpillars are small, and slug-shaped, as are most caterpillars of the Lycaenidae. Fully-grown caterpillars are extremely variable in colour ranging from green to grey or pink with markings picked out in dark green, pink, white or brown. The skin is covered in tiny bristles and appears velvety. The bristles also vary in colour. The larvae eat the ovaries and seed pods of the flowers, or the growing shoots of the plant. They grow from 1mm to 13-15mm long in three or four moults over a month to six weeks. They have a ‘honey gland’ on their rear segments like many other Lycaenidae, which attracts the attentions of ants.

Leptotes pirithous

Zebra Blue pupae are smooth-skinned with tiny bristles. They vary in colour from watery green to pale brown with a varying amount of black or brown speckling. The caterpillars pupate on their host plant among dead flowers or leaves, or on stems. They are attached by tiny hooks on their tail to a silken pad spun by the larva and by a silken girdle around their ‘waist’. They are about 7-9mm long, and of a typical rounded Lycaenid shape. The adult normally emerges in about three to four weeks although it can be as quickly as two weeks.

Host plant

Zebra Blue caterpillars feed on plants like Leadwort Plumbago auriculata, a popular garden plant. Few gardens that have this will not have these little Blues flying around it. All the Leptotes use other plants in the Pea family, Fabaceae. Indigoes Indigofera sp. are popular, as are Rattle-pods Crotolaria sp. and Cow-peas Vigna sp.

How to attract them

Gardeners can encourage the presence of this butterfly by planting any of its host plants, which is quite easy to do as there are so many of them and they are good garden subjects in themselves. Not only do they provide food for Zebra Blue caterpillars, but they are also among the finest nectar plants for all butterflies, especially Leadwort.

Leadwort makes a good hedge, particularly when planted with Cape Honeysuckle Tecoma capensis.

Black-eyes

EASY GARDEN BUTTERFLIES

Lilac-based, Plain, and Cape Black-eyesLeptomyrina gorgias, henningi, and lara

There are four species of Black-eyes in South Africa, all in the Lycaenidae (Gossamer-winged Butterflies), subfamily Polyommatinae (Blues, Bronzes, Hairstreaks etc.). Three of these are very similar to one another, are found in differing parts of the country, and all occur in gardens. The fourth species, Tailed Black-eye Leptomyrina hirundo, is smaller, has a dark blue upper side, and has long hindwing tails. It is seldom seen in gardens.

These are small (wingspan 20-30mm) low-flying butterflies found across South Africa’s provinces. Cape Black-eye occurs in the Fynbos and Karoo biomes, Brown Black-eye in the central savanna and grasslands, and Lilac-based Black-eye on the mountains and on the seaward side of the Great Escarpment. 

They have in common warm brown upper sides and a prominent white-ringed black eyespot at the lower corners of the forewings. Cape Black-eye has a coppery shade similar to the Plain Black-eye, and the Lilac-based Black-eye, as its name suggests, has greyish-mauve bases to the upper sides of the wings. The undersides of all of them are whitish-grey with dark speckles.

Males choose a perch on the side of a bush or on a prominent rock and fly off to chase other butterflies. They fly fast but settle often and readily open their wings to reveal the upper side. The females exhibit similar coloration and patterning as the males; however, they possess broader wings, exhibit slower flight, and are frequently observed on flowers. 

Distribution

Black-eyes can be found nearly all over South Africa. They overlap, and the Plain and Lilac-based intermingle and are thought by some to be merely different colour forms of the same butterfly species. Cape Black-eye is only found in South Africa and Namibia but the other two species are found further north in Africa as subspecies.

Female Black-eyes lay tiny, white or cream eggs singly on the succulent leaves of the host plant. They are 0.75-0.9mm diameter by 0.4-0.5mm high. They are domed with a pattern of white polygons, making them resemble tiny golf balls. They have a prominent dark mark at the centre of the top. The egg stage lasts about five to eight days.

Black-eye caterpillars are small, and slug-shaped, as are most caterpillars of the Lycaenidae. Fully-grown caterpillars are translucent green with a faint pink line running down the back and wavy pale diagonal lines along the sides. The row of black dots along the side are its spiracles through which it breathes. The skin is covered in tiny bristles and appears velvety. They are leaf-miners, spending their entire lives as larvae inside the host plants’ succulent leaves. They create cavities that fill up with their frass pellets (dung).  They grow from 1mm to 22-24mm long in three or four moults over a month to six weeks. They have a ‘honey gland’ on their rear segments like many other Lycaenidae, which attracts the attentions of ants. The ants have been seen removing frass from the leaf cavities.

Lampides boeticus

Black-eye pupae are smooth-skinned and vary in colour from watery green to pale brown with a varying amount of black or brown speckling and a darker reddish line running along the top of the abdomen. The caterpillars pupate near the host plant but will usually crawl out of their home leaf and move into the debris at the base of the plant. They are attached by tiny hooks on their tail to a silken pad spun by the larva on a stem, twig, dead leaf, or piece of debris and by a silken girdle around their ‘waist’. They are about 10-13mm long, and of a typical rounded Lycaenid shape. The adult normally emerges in about three to four weeks.

Host plant

Black-eye caterpillars feed on many species of succulent plants in the Crassula family. These include Pig’s-ears (Cotyledon orbiculata), Pygmyweeds and Stonecrops (Crassula and Kalanchoë), many of which are popular garden plants.

How to attract them

Gardeners can encourage the presence of this butterfly by planting any of its host plants, which is quite easy to do as there are so many of them and they are good garden subjects in themselves. Not only do they provide food for Black-eye caterpillars, but they are also among the finest nectar plants for all butterflies.

These plants do well in rockeries, formal herbaceous borders, and grassland gardens. Some other butterflies like Ciliate Blues (Hairtails) also use them as host plants.

Pea Blue

EASY GARDEN BUTTERFLIES

Pea BlueLampides boeticus

The Pea Blue (which is also known as ‘Long-tailed Blue’) is one of the Lycaenidae (Gossamer-winged Butterflies), subfamily Polyommatinae (Blues, Bronzes, Hairstreaks etc.). Blues are tiny to small butterflies, many of which have brilliant blue uppersides (although some are dull grey or brown). 

The male Pea Blue’s wingspan is 24-32 mm, the female’s, 24-34mm.

Males choose a perch on a tall herb or on a prominent rock and fly off to chase other butterflies. They fly extremely fast but settle often and readily open their wings to reveal the upper side. Males are bright blue above with patches of darker blue which are visible in flight, making them unmistakable to the trained eye. Females are a duller shade of blue with wide grey-brown borders and white marks around the edges of the hindwings. They are more often found on flowers and around their host plants.

The underside of both sexes’ wings is warm grey crossed by fine white bands and a thicker band along the outer edge of the hindwing. Each hindwing carries a short tail close to two black spots on both wing surfaces, that give the impression of a ‘false head’ as do many other ‘Blues’. 

Distribution

Pea Blues are extremely widespread, being found nearly all over South Africa. They are found across the ‘Old World’ (Africa and Eurasia), Australia and New Zealand. They have also reached the Hawaiian Islands. They may have followed man and his crops around the globe. Cultivated peas – Pisum sativum – are a listed host plant.

The female Pea Blue lays her tiny, pale blue-green eggs singly or in small groups on buds, leaves, or seed pods of the host plant. They are about 0.5mm diameter by 0.3mm high. They are flattened discs ornamented with a pattern of white moles, connected by tiny ribs in a pattern of triangles and a prominent dark mark at the centre of the top. The egg stage lasts about five to eight days.

Pea Blue caterpillars are small, and slug-shaped, as are most caterpillars of the Lycaenidae. This species’ fully-grown caterpillars vary in colour depending on the colour of the plant they are eating. Common colours are pea green, olive green, dirty white or pale brown. The markings vary from darker green to pink or brown. There is a dark line along the back, a pale line along the sides, and oblique pale lines in between. The skin is covered in tiny bristles. They feed on flower buds, flowers, and seeds of the host plants. They grow from 1mm to 20mm long in four moults over a month to six weeks. They have a ‘honey gland’ on their rear segments like many other Lycaenidae, which attracts the attentions of ants. Image © John Joannou♱

Pea Blue pupae are smooth-skinned and vary in colour from cream to brown with a varying amount of black or brown speckling and a dark line runs along the back. The caterpillars pupate near the host plant but generally crawl out of a seed pod or away from a leaf and move into the debris at the base of the plant. They are attached by an adhesive smeared by the larva on a stem, twig, dead leaf, or piece of debris with a silken girdle around their ‘waist’. They are about 10-13mm long, and of a similar shape to those of the Geranium Bronze, but lack hairs. The adult normally emerges in about two to three weeks. Image © John Joannou♱

Host plant

Pea Blue caterpillars feed on many species of leguminous plant, not only cultivated peas. These include Rattle-pods (Crotolaria), Indigos (Indigofera), Lucerne (Medicago sativa), Sweet-peas (Tephrosia), Milkworts (Polygala) and Cow-peas (Vigna), many of which are popular garden plants.

How to attract them

Gardeners can encourage the presence of this butterfly by planting any of its host plants, which is quite easy to do as there are so many of them and they are good garden subjects in themselves.

It’s important to also have nectar plants in your garden, as well as open sunny areas with structure like prominent rocks and trees or shrubs that the males can use as territorial markers.
